Vegetation is an important part of ecosystem and estimation of fractional vegetation cover is of significant meaning to monitoring of vegetation growth in a certain region. With Landsat TM images and HJ-1B images as data source, an improved selective endmember linear spectral mixture model (SELSMM) was put forward in this research to estimate the fractional vegetation cover in Huangfuchuan wate...

In this paper, the electrical characteristics and sensitivity analysis of staggered type p-channel heterojunction electron-hole bilayer tunnel field effect transistor (HJ-EHBTFET) are thoroughly investigated via simulation study. The minimum lattice mismatch between InAs/GaAs0.1Sb0.9 layers besides low carrier effective mass of materials provides high probability ...

During the first steps of site-specific recombination, Cre protein cleaves and religates a specific homologous pair of LoxP strands to form a Holliday junction (HJ) intermediate. The HJ is resolved into recombination products through exchange of the second homologous strand pair. CreH289A, containing a His to Ala substitution in the conserved R-H-R catalytic motif, has a 150-fold reduced recomb...

Though it arouses more and more curiosity, the HJ iterative algorithm has never been derived in mathematical terms to date. We attempt in this paper to describe it from a statistical point of view. For instance the updat ing term of the synaptic efficacies matrix cannot be the gradient of a single C a functional contrary to what is sometimes understood. In fact, we show that the HJ algorithm is...

Phenanthrene (PHE) is one of the model compounds polycyclic aromatic hydrocarbons (PAHs). In this study, a natural PHE-degrading microbial consortium, named HJ-SH, with very high degradation efficiency was isolated from soil exposed to long-term PHE contamination. The results GC analysis showed that consortium HJ-SH degraded 98% 100 mg/L in 3 days and 93% 1000 5 days, an higher than any other c...

The Holliday junction (HJ) is a central intermediate of homologous recombination. Its cleavage is critical for the formation of crossover recombinants during meiosis, which in turn helps to establish chiasmata and promote genetic diversity. Enzymes that cleave HJs, called HJ resolvases, have been identified in all domains of life except eukaryotic nuclei. Controversially, the Mus81-Eme1 endonuc...
